my task is to control a machine (process control) has no first principle model(mathematical model), but we manage to collect real data from this machine, i.e flow rate and concentration of liquid, i would like to design a feedback controller for this machine (PID) and i need your help to advice me with the right step that i can start with. i tried system identification and i will appreciate if you could advice me with the right way (guide).
for the hard ware i think PLC is the best option to use so is there away to convert the Matlab simulink if i get success designing the controller to PLC, and VFD will be used to control the feed rate of the pump.
thank you very much and i am looking forward to hearing from you.
